To realize the high efficiency of dernisting, thenew type cathode wires and anode tubes with superperformance were developed for increasing the current density and field intensity.

实现除雾高效化，关键在于研制高性能的新型阴线管，高度场强度。

At the end of the experiment, a defogger automatically cleans the inside of the testing chamber for specimen.

实验完成后，具有全自动除雾装置，可清晰的观察实验室内之试品。
